Hi Rowland Finally, my DC and domain member are in a good state and I was able to authenticate a user using the ntlm_auth program that I ran on the member host. I will describe the solution first because it may be helpful for others. I've also put down couple of things that still perplex me (room for improvement perhaps) I'm running a radius server on a Ubuntu host (named RadSrv) and it

Hello Tim, Hello samba-people, is there an uptodate guide for authenticating via freeradius somewhere? I have some Ubiquiti APs plus a Cloud Key and I want to authenticate WLAN clients via WPA2-Enterprise instead of a (shared) PSK. It seems like https://wiki.samba.org/index.php/Authenticating_Freeradius_against_Active_Directory is missing some steps (basic setup of freeradius). Can you

Hai, It does not happen often but yes, i also need some help as i cant know everything also and im new with freeradius. Im working on a configuration for samba member + freeradius with ntlm_auth. Why ntlm_auth, because the next one is kerberos and ldap auth to configure.. I want to have some fallback options here and you have to start somewhere. This is running on my new proxy/gateway

I can share my notes, we authenticate UniFi clients via Freeradius against Samba AD. We also check group membership which you might or might not need: ## 4 FreeRADIUS ### 4.1 Basics ```bash apt install freeradius freeradius-ldap freeradius-utils # create new DH-params openssl dhparam -out /etc/freeradius/3.0/certs/dh 2048 ``` ### 4.2 Configure Authentication - modify mschap to use winbind,

Hi Alexander, I'm terribly sorry. We didnt have the "ntlm auth" parameter configured on the DCs at all. I added it and it just works. Thanks for your help. Now I just need to figure out how I can make WLAN-specific LDAP-Group authentication. e. g. production WLAN needs LDAP group "wlan_production" and management WLAN needs the "wlan_management" group. I

Hello Alexander, thanks Alexander for these configuration snippets. Which version of Samba are you using? Is this on debian bullseye? Is the FreeRADIUS server installed on a DC or on a Domain Member? (I just tested the latter). is "ntlm auth = yes" OK for the DCs and the domain member or does it have to be "mschapv2-and-ntlmv2-only" for all servers (DCs + Member)? It

Hi Matthias, we?re using Debian Bullseye with the backports repo. So version is a mixture of - Samba version 4.17.3-Debian - Samba version 4.17.7-Debian We?ve installed it directly on the DC?s as well. In my opinion using "ntlm auth = yes? should be fine. Did you try using a simple RADIUS secret? In my experience long secrets or ones containing special characters don?t work very well. I

Hi, My goal is to make use of samba 4 and freeradius to authenticate user to use wifi network (WPA2 enterprise). The setup is to setup Samba 4.0.3 in machine A and setup freeradius in machine B. By reading: Document A: http://wiki.samba.org/index.php/Samba4/beyond Document B: https://wiki.samba.org/index.php/Samba4/HOWTO/Virtual_Private_Network Document C:

Hi there, I'm trying to get FreeRADIUS to authenticate against my Samba DC. It's Samba 4.7.6-ubuntu running on Ubuntu 18 (kernel version 4.15.0-66-generic). It came nicely packaged with Zentyal, which provides a nice GUI for managing a domain, as well as a CA and lots of cool small features. That same Zentyal also includes support for FreeRADIUS (3.0.16). This is my smb.conf:

Hi, I recently noticed that two separate Windows 11 machines joined to my domain are not letting me log in to them as a domain user. In the Windows Security event log I can see 'Audit Failure' - 'An account failed to log on'. Details shown are: 'Account for which logon failed' - 'Security ID: NULL SID'; 'Account Name: myusername'; 'Account Domain:

Hi, We've been having an intermittent issue with pam_winbind on Ubuntu 24.04. The test case we have to demonstrate this is to run this loop after logging in as a domain user: $ while sleep 1 ; do sudo -k ; sudo -K ; date ; echo "password" | sudo -S /bin/echo "sudo success" || break ; done The loop will run successfully, sometimes for 50+ iterations but eventually [sudo]

I've setup Samba as an AD-DC on an Ubuntu 22.04. My goal is to use it for testing PEAP MSChapv2 authentication on a Radius server where I want the Radius server to validate the MSChapV2 Challenge-Response sent by the client by talking to the Samba DC ecosystem. I'm using the ntlm_auth program to talk to Samba and it works as expected when I run it on the DC host in a bash shell like so:

Hello All, Please help.. I can not join an additional new samba dc ver. 4.19.5 to an existing samba Ad version 4.19.5 functional level 2008 R2. Last week I successfully demote an offline dc3 and move the fsmo role to dc4. The command i used to join: it at dc6:~$ sudo samba-tool domain join NICHO.COM DC -UAdministrator at NICHO.COM --option='idmap_ldb:use rfc2307 = yes'
